German Climate Computing Centre

The German Climate Computing Centre is a major European research institute located in Hamburg that provides high-performance supercomputer resources and data services for climate change science, atmospheric science, and oceanography. It supports modelling efforts used by the Intergovernmental Panel on Climate Change and national programmes such as the German Climate Consortium and collaborates with universities, federal agencies, and international laboratories. The centre's work underpins assessments like the IPCC Fifth Assessment Report and contributes to operational systems such as the European Centre for Medium-Range Weather Forecasts.

Overview

The centre operates as a national node for climate modelling and data archiving, serving projects from groups at Max Planck Society institutes, Helmholtz Association centres, and university departments including University of Hamburg, University of Bremen, and Freie Universität Berlin. It hosts infrastructure that supports model intercomparison projects such as CMIP6, observational synthesis initiatives like Argo (oceanography), and impact studies informing the United Nations Framework Convention on Climate Change and the Köppen climate classification-related research. The centre interfaces with operational agencies including the Deutscher Wetterdienst and international consortia such as Copernicus Programme and the World Meteorological Organization.

History and Development

Founded in the context of German and European investments in computational climate science, the centre emerged during expansions of the European Union research infrastructure and collaborations with the National Center for Atmospheric Research and Met Office. Early phases involved partnerships with the Max Planck Institute for Meteorology and the Alfred Wegener Institute to curate model output and observational datasets. Milestones include contributions to the IPCC Fourth Assessment Report and hosting technology transfers with the Lawrence Livermore National Laboratory and Oak Ridge National Laboratory. Developments tracked advances in processor architectures from vendors such as Cray (company), IBM, and Fujitsu.

Facilities and Infrastructure

The centre's hardware stack comprises petascale supercomputer systems, high-capacity data center storage arrays, and high-bandwidth networks connected to European backbones like GÉANT and research infrastructures including PRACE. Onsite facilities include climate data archives for projects tied to PANGAEA (data publisher), observational repositories using standards from European Space Agency missions such as Sentinel (satellite constellation), and metadata catalogues aligned with World Data System. Computational environments support model frameworks from groups like ECMWF Integrated Forecasting System, CESM, and ICON (model), and experiment workflows for CMIP and CORDEX.

Research and Services

Research supported by the centre spans numerical modelling of atmospheric circulation, ocean dynamics tied to NOAA datasets, cryospheric studies relevant to Alfred Wegener Institute programmes, and Earth system analyses linked to International Geosphere-Biosphere Programme themes. Services include archive curation for the Coupled Model Intercomparison Project, data dissemination for Copernicus Climate Change Service, and user support for research teams from University of Oxford, ETH Zurich, and Sorbonne University. The centre provides training linked to workshops by European Space Agency and delivers compute time competitive allocations like those managed by PRACE and national programmes analogous to NWO calls.

Partnerships and Collaborations

Collaborations extend to European partners including ECMWF, Met Office, Météo-France, and national institutes such as Institut Pierre-Simon Laplace and the Finnish Meteorological Institute. Global links include technical exchanges with NOAA, NASA, CSIRO, and the Canadian Centre for Climate Modelling and Analysis. The centre contributes to coordinated efforts like Global Climate Observing System and participates in data standards working groups with WMO and the International Council for Science. Academic alliances include project work with University of Washington, Columbia University, and the University of Tokyo.

Governance and Funding

Governance structures connect the centre to German federal ministries and research organisations including the Federal Ministry of Education and Research (Germany), the Helmholtz Association of German Research Centres, and the Leibniz Association through programmatic agreements. Funding streams combine allocations from national budgets, competitive grants from the European Commission framework programmes such as Horizon 2020, and partnerships with industry vendors like Intel Corporation and NVIDIA. Oversight involves advisory boards with representatives from institutions such as Max Planck Society, Deutscher Wetterdienst, and international stakeholders from World Meteorological Organization and IPCC communities.
